The haptic feature also packed in last year iPhone 6S, even though, it doesn’t work for the home button. And, recently launched iPhone 7 and iPhone 7 Plus coming with Taptic Engine (Physically Contact with Home button) for better haptic feedback than ever before. It gives real Sense of touch either you clicking single or pressing twice you pull down the Notification Center, etc. It needs enough presser so that you will not press it by accidentally. Besides, Apple has also opened the door for developers, since the company provides new API for them (developers) to add custom vibratory feedback to their applications. In the short term, in gorgeous iPhone included a haptic engine is a form of MacBook trackpad. If you dislike this vibratory feeling, then you may control it means to enable/ disable haptic feedback on iPhone 7 or iPhone 7 Plus, iPhone 8, 8 Plus.

I recommend that you should Turn on haptic feedback for getting something new user interface feels Cause haptic feedback is only a single setting for System Controls and interactions. By the way, you can turn off it by following steps.
